I was looking today at this 1774 Anhalt mining Taler. As was typical of the mining Talers of the Harz region, even in the late 18th century it was struck in Feinsilber (fine silver, in theory .993 pure, although the silver itself was not completely pure so in practice it might be closer to .95. ). However, to offset the fine silver, it weighs only 23.32 g. With a 38 mm diameter, I think it still qualifies for this Silver Crown-size thread.
